Generative Waveform Design Methods in Complex Electromagnetic Spectrum Scenarios

With the development of complex spectrum environments such as 5G and 6G, the utilization of electromagnetic spectrum resources has become increasingly intensive, imposing higher demands on the performance and adaptability of traditional radar systems. The fixed waveform design approach commonly used in traditional radar systems is easily identifiable and prone to interference in complex spectrum environments, making it difficult to meet dynamically changing mission requirements. To address this challenge, this paper proposes a generative waveform design method suitable for complex spectrum environments. This method constructs a performance envelope based on radar mission requirements under multiple constraints and generates a feasible waveform set through constrained rule-based searches, thereby enhancing the flexibility and adaptability of waveform design to the environment. Experiments demonstrate that the proposed generative waveform design exhibits greater robustness and anti-interference capabilities in complex spectrum environments. Comparative analysis using classic clustering and sorting algorithms further validates the effectiveness and superiority of this method over traditional fixed waveforms, providing new insights for the design and optimization of radar systems in complex spectrum environments.
